SAW-CLAMP- SPECIFICATION forming part of Letters Patent No. 788,962,dated May 2, 1905.

Application filed April 12, 1904:. Serial No. 202,786.

To (1/7 whom it may concern.-

Be it known that I, MONT W. STOUGHTON, a citizen .of the United Statesof America, residing at Magic, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements inSaw-Clamps, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention has relation to saw-clamps for holding saws while theyare being sharpened, and has for its object the provision of a saw-clampof novel character adapted to be detachably applied to an ordinarybench-vise.

In carrying my invention into effect I provide two clamping-jaws each ofthe same construction as the other and such jaws being so formed thatthey may be applied to the jaws of a bench-vise of the ordinarycharacter or a vise of the novel construction hereinafter described,saw-clamping jaws being provided with means of attachment whereby theycan be easily and rapidly secured on the vise-jaws or detachedtherefrom.

My invention consists in the novel construction, combination, andarrangement of parts to be hereinafter more fully described and claimed.

In the accompanyingdrawings, Figure 1 is a side elevation of abench-vise having my improvements applied thereto. Fig. 2 is a frontView of the same.

The vise shown on the drawings is composed of a body portion 1, havingears 2, pierced for the passage of bolts by which the vise is fastenedto the bench. the ways 3, the stationary jaw 4, the screw 5, the handle6, and the sliding jaw 7. The jaws 4 and 7 have the inwardly-turnedupper ends, which when the vise is used in theordinary manner abut oneagainst the other to clamp the material to be held in the vise.

My improved clamp consists of two similar members which are of the samesize and construction, each being formed with a horizontal clampingjaw9, which isjoined by diagonal bars 10 l0 and a vertical bar 11 to thebase 12. The inner faces of the bases 12 12 are flat and lie in the sameplane With the inner faces of the jaws 9 9, so that when a saw is placedin the clamp it will be simultaneously gripped by the jaws 9 9 and theflat faces of the bases 12 12. which thus constitute supplementary jawswhich grip and sustain the sawblade below the main jaws 9 9 of the clampand assist in preventing the saw-blade from moving or vibrating while itis being sharpened or otherwise treated.

The bases 12 12 are formed with curved arms 13 13, that overlap theouter surfaces of the jaws 4; and 7 of the vise and are provided withthe curved arms 14: 14, that fit within the jaws 4 and 7 when the clampis in position on the vise, as shown in Fig. 1 of the drawings. The jawsA and 7 of the vise are provided with screw-threaded holes that receivescrews 15 15, which pass through holes in the curved arms 13 13, whichscrews are provided with flat heads or thumb-pieces 16 1 6, by means ofwhich the screws may be driven into screwthreaded holes in the jaws 4and 7.

A clamp constructed as above described is applied to the vise in theposition shown in the drawings and when so applied constitutes anattachment by means of which a saw can be very securely held in positionwhile it is being sharpened, set, or otherwise treated, and in securinga saw in position it is arranged between the two sections of the clampso that it will be clamped near its toothed edge by the jaws 9 9 andnear its opposite edge by the flat faces of the bases 12 12. Theclamping members are brought together and separated by operating thevise in the usual manner that is, by turning the screw 5 in onedirection or the other by means of the handle 6.

Having fully described my invention, what In testimony whereof I aflixmy signature in the presence of two witnesses.

MONT W. STOUGHTON.
